Good rate on insurance in Texas for Model S

Progressive just gave me a ridiculously high quote on Model S (even though they are great with a Roadster). Geico has said they won't insure either car in Texas, even though they do in California. Anybody have any good suggestions for an insurance carrier in Texas?

Called Geico a second time, and got a much better rate - they blew Progressive out of the galaxy. Roughly $250 for the S for six months. Definitely worth it to call the same company twice if you're not happy the first time.
